.LAUbwI'S Patent No. 109,383, dated November 22, 1870 antedated November 9, 1870.

IMPROVEMENT IN TINNERS FIRE-POTS.

The Schedule referred to 'in these Letters Patent and making part of the same.

To all whom it may concern v Be it known that we, FRANK M. CAMPBELL and Lonnxzo W. BROWN, of Cleveland, in the county of Ouyahoga and State of Ohio, have invented a certain new and improved 'linners Fire-Pot; and we do hereby declare that the-following is a full, clear, and complete description of the same, reference being bad to the accompanying drawing making part of this specification.

Description.

Figure l is a front View of the pot.

Figure 2, a view of the top;

Figure 3, a vertical transverse section.

Figures 4 and 5, detached sections.

Like letters of reference refer to like parts in the several views.

This invention has for its object a fire-pot for burning charcoal, dust, or waste, for the purpose of heatiug tinncrs irons, thereby utilizing the waste, and thus cconomiziug in the consumption of coal, in the m a n ner as hereinafter described.

In the drawing, fig. 1-

A represents the tire-box of the pot,.of which E is the mouth into which the irons are iusertedfor heat ing., I

It will-.hc observed that the box is tapering downward to the gratcO, and that the top of the box is partially covered by a perforated ring, 1), having a large central opening forming the coal-chamber o; stack E, into which the coal is put for supplying the tire.

F is an annular due, of which the perforated rim referred to forms the bottom, and a series of perforations, at, the draught-Miles communicating with the fii'O-bOX and flue.

Said flue connects with and discharges into the stack or smoke-pipe (i.

H is adainper lying upon the bottoin oi the annular due, as shown in iig. I), and whereby the draughtholcs a may he closed for shutting oii the draught, when rcquircd.

I is illlGgjlb'li-l'litil, in which ihciirc-pot stands for safety and for catching the ashes as they faltfrom the grate.

It is well known to those using wood-,coal that,

is thrown away, thereby resulting in a considerable loss to the consumer.

'lo utilize this waste by-b-urniug it is the purpose "of this invention, and which is done by confining the draught to the lower part of the fuel instead of having the draught through the entire mass of coal in the/M pot, as in the common fire-pot.

in our pot the fire is confined whollyiu the fire-box A, the draught of which is through the holes a into the annular flue immediately above the iirc.

By this means a strong draught is obtained, and which, having to pass through only the lower portion of the fuel, instead of ascending through anyconsiderablc body of it, the coal, however fine, will burn, as the draughtis not choked by the mass of coal above In this fire-pot the finest coal-dust is easily and readily burncd without the assistance of coarse coal in order to keep it open and free for a draught.

The ashes arc shaken from the fire by the grate C, which may be shaken from the ii'ontfor that purpose; hence the fire can at all times be kept clear of ashes and glowing with. heat, whereas the upper part of the fuel in the coal-chamber or stack 15 will remain unignitcd, and therefore not burncd usclcssly, as the cover J cii'cctually stops all draught in that direction,.f

the draught being as indicated by the arrows, and not up through the coal in the chamber i as aforesaid.

Claim.

What we claim asour invention, and desire to securc by Letters Patent, is

A fire-pot, when constructed with an annular flue, 1 provided with a perforated bottom, 1), damper H,

and fire-box A, substantially in the manner as dcscribed, and for the purpose specified.
